New MH bulb not firing up?

I just got some new MH bulbs. One of them is working perfectly, but the other is malfunctioning or something? Should I get an exchange?

The ballast is somewhat old, but it works perfectly. I opened it up and the ballasts and capacitors are still in good condition. No loose wiring or connections. I even pulled the connector inside the socket out a bit to get a better connection, but nothing.

Here's a picture with all the specs on the bulbs. It's the 8,000k bulb.

Here's a video of the bulb not firing up. After it cuts out, it'll begin to start up and cut off.
